All types of oil seeds contain a varying amount of oil content in them. The oil that comes from these seeds are used for many purposes such as cooking, pharmaceuticals, soaps, cosmetics, and many more. In order to extract the oil from these seeds, the process of crushing seeds is carried out. Although during the earlier times, traditional methods of crushing seeds by grinding was used. This grinding process was not very effective as the yield of oil was not much. With the rise in technology and science, the use of machines like oil expellers was started. The oil that is extracted with the use of these equipment was of a large quantity as well as purest quality. This is so because the use of full press expellers don't need the extraction of oil through chemical treatment.

Oil Expellers are of two types i.e., Pre Press Expeller and Full Press Expeller. While the pre press expeller is used in large capacity oil plants, full press for small scale oil mills. In the oil extraction process done with the use of full press expeller extracts the maximum yield of oil from the oil seeds. This leaves the residual oil cakes with very less amount of oil content that ranges from 5-8%. The preparation and the extraction processes of these both types of expellers are the same, but what differs is the amount of oil yield. Also, the solid residue from pre pressing is used for solvent extraction process so that the remaining oil can be extracted from it.

In today's market, a large assortment of Full Press Expellers is available at very minimum cost. These are given a sturdy and strong construction, and provide very efficient results. The major advantage of using this type of expeller is that it increases the yield of oil by a large amount. The quality of the oil is also pure and healthy as the process is not chemically treated. Full press expellers are used to extract oil from all kinds of oil seeds and nuts like:
  • Sunflower seeds
  • Cotton Seeds
  • Mustard seeds
  • Copra
  • Groundnuts
  • Lin seeds
  • Flax seeds
  • Soybeans, and many more.
